The prenatal examination was normal, and the child was born with cerebral palsy. What's going on here?

The current prenatal examination is not 100% accurate. After all, not all abnormalities can be detected, especially in this special part of the brain. It is not excluded that cerebral palsy is caused by lack of oxygen during childbirth. Clinically, it has also happened, and the news media has reported that in the process of delivery, because the child can't give birth naturally, he will eventually form cerebral palsy due to lack of oxygen during delivery, but this situation is not particularly common, accounting for about 10%. According to the current medical means, this probability has been reduced to a minimum. Once dystocia is found, they will have a caesarean section in time, so as to avoid the occurrence of cerebral palsy.

The cause of cerebral palsy is mostly brain injury or deformity, but some cerebral palsy is not deformity, but is caused by dysplasia during development. Prenatal examination also has some limitations. Prenatal examination can only find out whether the fetus has obvious malformation during pregnancy. After all, prenatal examination can see a general development of the child, but there is no stronger penetration to check the development of the brain. Fetal cerebral palsy may also be due to dysplasia, or even because pregnant women were injured during pregnancy.

Virus infection or poisoning, as well as parasites or genetic diseases can lead to baby cerebral palsy. In fact, the accuracy of prenatal screening is not necessarily 100%. After all, there may be no problem before prenatal examination, but in later life, some viruses or bacteria invade the body, which eventually leads to fetal brain dysplasia.

For example, there is a Toxoplasma gondii in animals. This parasite is actually very harmful to the baby's vision, which may not be detected during prenatal examination. Therefore, as a pregnant mother tomorrow, we must pay attention to hygiene. Besides, don't keep some animals at home after you plan to have children. After all, animals are susceptible to parasites, viruses and germs.
